A male Kolaran
Kolarans are a humanoid pre-warp civilization located on Kolarus III. These humanoids live in isolated pockets at an early stage of industrial development, comparable to mid-20th century Earth.
In 2379, the Kolaran natives encountered an armed away team from the USS Enterprise-E that had invaded their territory to salvage the android B-4. The natives attacked the away team, but the team's highly superior technology allowed them to escape unharmed. (Star Trek Nemesis)
Although not identified on screen, the name "Kolarans" is derived from production notes during the making of Nemesis.
The hand weapons used by the Kolarans are actually prop replicas of real present-day weapons with olive-colored fabrics wrapped around various sections. As shown by the It's A Wrap! sale and auction, these weapons are replica Valtro shotguns and FN P90s.
